msnen-nine PLACER.

To all whom t may concern-.A j i Be it knownE that I, EDISON MoPnnK, a citizen of the United States,-and a resident of Sardis,in the county o'fMonroe andState of Ohio, have invented anew and Improved Piston-Ring Placer, of which the 4following isa full, clear, and exact description.

This invention relates to improvements in piston ring placers, an obj ect of the invention being to provide an apparatus which will expand a piston ring, hold lit inproper position on a piston and eject the ring into a piston groove.

A further object is to provide anapparatusof the character describedivhich is capable of use in connection with any size of piston ring andfivhich can be quickly. and conveniently manipulated to lposition the ring on the piston.

With these and other objects in view the invention consists in certainfnovel features of construction, andc'ombinations andarrangements of parts as Will'be more fully hereinafter described and pointed Vout in the claims.

In the accompanying drawings-- r Figure l is aviewpartly in elevation but mainly in vertical longitudinal section through the centerof theapparatus showing it in operative position.

Fig. 2l is avievv'in` transverse section on the line 2 #2 of Fig. l.

F ig.. 31is a'view in transverse section on the line 3'3fof Fig.1. j

Fig. l is a fragmentary side elevation of one of the piston ring holdingY feet.

1 represents the lordinary form of4 engine piston having piston ringfreceivingf grooves 2. My'iniprovedpiston ringy placer isf-provided With a frame 3 having preferablyV three radially extending slotted arms 4J and 4ta, thelat-ter provide'dat itsou'ter end With an upwardly projecting bracket 5 and said frame atr its centerniade` with a cylindrical upstanding hub 6 with alradially projecting handle v7 integralv|` therewith.

A sleeve 8 islmounte'd toslide on the upstanding hub 6v andisfprovided iviththreeV radially'projeeting arms 9 disposed above theV frame l' arms 4 and havinglongitudinal slotsflO inthei'r free ends. A vertically adjustable rod 11 is mounted to slide'freely in the hub 6 and is-iscreviT threaded at its upper end as'shown at 12, 'for'the acccomrn'odation of relatively long adjusting Wing nut 1 3, the4` latter externally screvv` threaded Specification of Letters Patent.

atk its lower end as shown at 14, for' the reception of a nut 15.

The adjusting nut 13 is carried by and Vhas rotary/'mounting in the intermediate portion Oi' alever 16, said lever havingan opening 17 Ato receive the nut 13, and said nut 13 having aishoulder 18 thereon between which shoulder and the nut 15 the lever 16 is locatedso that the movement of the lever and the nut 13 is always the same. In Aother Words, can be varied by the; movement of the nut 13 and the movement of the nut 13 andv the rod 11 With Which it i'sfco'nnected5 is controlled by the position oflever 16 so that While the nut 13 operates to adjust the rod 1 1 verticallj7 relative to the lever, the operation of the lever controls thevertical Inovement of the rod. The lever 16 is pivotally connected at one end to a postv 19 integral with the bracketl 5; the pivotal connection being' indicated by the reference character 2O.V i

The lslotted arms l of the frame 3 receive and support bars`21, said bars movabley radially of theslotted arms .land having rollers 22at`their upper ends `supported On said arms. Thesebars 21 are pivotally connected by links-23fvvith the rod 11 so that the longitudinal movement of the rod '11 causes the bars 21 to be movedradially and *coiled springs 24C connect certain of these bars 21 with the rod 11-so as to r exert a spring tension to hold the partsin' normal position and return them to such positionwhen permitted.

On the lower ends o'l the bars 21 piston ring supporting feet' 25 are removablyiconnected so that eetof various' sizesmay be used in: accordance Withthe" Width of the piston ring to be placed. These feet 25 have extended beveled toes' 26 adapted to engage the inner face of apiston ring 27 and hold the piston ring in expanded condition ready for insertion on the piston 1. 'i

Ejectors 287 which are in the form of rela-Y tively long barspare located beside the bars 21 andinova'blel in guide brackets 29 on said bars. The upper ends of theser ejector bars 28 are bifurcated to straddle the slotted ends 10 of the arms 9 and are provided with pins 30 extending through the slots 10 so 1that the movement-of the arms 9 `controls the longitudinal movement of the ejector bars 28. Thelovver end of these ejector bars 28 have inwardly extending nngers 31" which are' `lothe position of the lever` soV l sary diameter,

,move downwardly, x lower ends of: these piston ring 27 off `of the feet 25 and allowV cated above the piston ring 27 and are pothe sleeve 8 and hub 6 and allow a VVfree movement of the lever 32. A spring 43 is located between the leverv 32 andthe frame 3 and exerts upward pressure on the latter.

A relatively long locking dog 35 is pivotally connected to the handle 7, as shown at 36, andprojects .through slots 37 and 38 in the levers 32 and 16 respectively and a coiled spring 39 connects .the dog 35 with the handle 7 tending to swing said dog in one direction. This dog 35 ismade with an enlargedhead 40 at itsupper free end and with a shoulder 41 at a point below the head so that the lever 161can be engaged either by the shoulder 41 or by the head 40 to control the position of said lever.

`The ejector lever` 32, above referred to, is provided in the `sides of its slotted portion 34 with. inwardly projecting pins 42 which project into the sleeve 8 so as to compel said sleeveto -move vertically on the hub 6 when lthe lever 32 is operated.

The operation is as follows :V The lever 16 is first moved to the position shown in Fig. 1 with the dog 35 having its shoulder 41 engaging over the lever 16 and holding the sameinf such position. The piston ring-27 is then positioned on the feet 25 and the wing nut 13 turned to move'the rod 11 downwardly, thus moving thebars 21outwardly to expand the piston ring 27 to a diameter suiiiciently large to pass freely overV the end of the piston 1. llVhile'in this, position the ring isilocatedover theV piston 1 and adjacent the rooves 2 into which it is vto be placed. T e operator then moves the dog 35 from its holding position to allow the lever 16 to move upwardly and thus quickly move Vthe bars 21 inwardly to permit theV piston ring 27 to contract. He then forces the lever 32 downwardly, and this movement of the lever. 32, through the medium of the sleeve 8 and arms 9,'causes theejector bars `28 to and the ngers 31 at the bars 28 will force the the ring to spring into the proper groove 2. It4 will thus be noted that withv my improved device a piston ring can be located on the feet 25, then expanded to the necesthen allowed to contract, Athen ejected :from

the device into the proper groove, and the operation can be performed easily and quickly without damage either to the piston orto the ring.

Various Vslight changesvmight be made inthe general formv and arrangement ofparts `alterations as fairly fall and means then positioned on the piston,l

described without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myselfr at liberty to Ina-ke such changes and within the spirit and scope of the appended claims.
